greater value to plant pathologists are the voluminous citations 

 and bibliographies, together with the abundant illustrations, 

 which include at least one for each genus of importance in the 

 United States. 



With the present vigorous prosecution of the study of plant 

 diseases, it is obviously inevitable that a book of this nature 

 should be out of date in some subjects the moment it leaves the 

 hand of the printer. But this hardly excuses the utter disregard 

 in a few places of researches of a number of years' standing, such 

 as those on Monascus, and those on Puccinia graminis by Pritch- 

 ard. It is, further, very unfortunate that poor proof-reading 

 should mar the text in other places, such, for instance, as on p. 

 80, where the past tense is used instead of the present; on p. 112, 

 "Bot. Gaz." for bot. Ges. ; on p. 142, "conidial" instead of 

 conical; on p. 143, "unknown on," apparently for known only 

 on; on p. 391, "Key to species," instead of Key to assignment 

 of species. On p. 366 is shown a rare instance of poor selection 

 of illustration. Each cell of the teleutospore should obviously 

 have but one basidium. A few of the illustrations might be 

 made more effective if labelled more clearly; such, for example, 

 as figs. TJ, 100, 173, 174, 249, 383 and 662. 



These defects fortunately detract but little from the great 



value and usefulness of the book, and there can be no doubt of its 



hearty welcome by plant pathologists.

Harper's Report on Forests of Alabama'^ 



This is an exceptionally valuable report since it not only con- 

 tains a vast amount of information about the forests of Alabama 

 but has it classified and arranged according to geographical 

 divisions of the state. This method has very decided advantages 

 over general descriptions, though it requires an extensive and 

 detailed knowledge of local conditions to be followed satis- 

 factorily.
